Gallery: Japanese Students Unveil Electric Roadway that Wirelessly Char...

 

One of the biggest hurdles that the electric car has yet to completely conquer is range anxiety – although improved battery technology allows for longer driving ranges, EV charging infrastructure is still in its infancy. A team of Japanese university students recently tackled the issue by demonstrating a new wireless EV charging system that could give electric cars a driving range on par with gasoline and diesel powered cars. Unveiled at Wireless Technology Park 2012, the EVER system is able to transmit electricity to a vehicle through a four-inch-thick block of concrete.

The university team’s project is named EVER (Electric Vehicle on Electrified Roadway) and its development is lead by Takashi Ohira, an electrical engineering professor at the Toyohashi University of Technology. This system would effectively do away with the charging cables that currently tether today’s EVs to the grid, and it could enable electric vehicles to travel hundreds of miles without having to stop for a recharge.

The team has developed an electric field coupling system to supply a charge to a car through its tires. In the recent demo, a metal plate was placed along with a four-inch layer of concrete, which represents the road surface. Electricity between 50 and 60 watts was successfully transmitted to standard size automobile tires.

This isn’t the first time that a team of engineers have tested the idea of an electrified roadway. Last year Toyota Central R&D Labs and Ohira tested a similar system. In order to make the system viable the electric power needs to be increased by at least 100 times, which is the group’s goal.

    SOLAR ENERGY SOON TO POWER THE WORLD

    ELECTRIC HYBRID VEHICLES & ELECTRIC VEHICLES SOON TO OUT SELL ALL OTHERS

    Energy has driven the world for over a thousand years Wind, Hydro and Solar are the oldest forms of energy giving power to all smart enough to use it.

    In the last 200 years Coal, Oil and Nuclear has given energy to many worldwide and great power and wealth to only a few. At the cost of many lives in coal Mines, Oil Spills, Radiation, Cancer and Polluting the Air and Water on all of the Earth.

    Unfortunately for the wicked there is not an unlimited amount of oil on earth. Just the same as the Forest Trees that clean the air and make Oxygen we breath and all living on earth need to Live. As some in denial are not able to recognize or ever see or live with blinders on.

    Doctors and Drug ceo’s have been making millions prescribing drugs to many that live near or by High polluted areas. From dirty energy that hurt breathing our lungs, water we drink and harm our children and all. That we all pay for. When all on earth need is Clean Air and Water, and Clean Cities.

    Now common sense would be for all to look for a Clean Fuel Source like Wind, Hydro, Geothermal and Solar. Renewable Energy is eliminating the need for Dirty Energy Worldwide at a record pace. With SOLAR ENERGY Clearly the front runner.

    To the fear of some of the richest people on Earth. They to surprisingly are doing
    something extraordinary investing in Solar Energy. After years of many of them trying to under mine it.

    Fuel that makes energy to ship goods, or make electric for homes and manufacturing. Can transform whole nations into prosperity and wealth or poverty and economic hardships for most all. Just as taxes on taxpayers has done. For over two thousand years. Making slaves of many to the wicked and unjust few. History Lesson Roman Empire, Persian Empire now OIL Empire oh sorry OPEC.

    The Freedom to get your own Power from the Wind and Sun, Solar Energy has been there for years. Are Libraries and Schools should have been the first to have gone Solar and Renewable Energy. And why are they not? Churches are all over the Planet. They are going to Solar Energy.

    Thank GOD for the Pioneers like John Schaeffer that Started Real Goods The first and Best catalog for Renewable Energy and Dr. Addison Bain one of NASA top Scientist and Scientist Bill Young at the FSEC Florida Solar Energy Center and Monica D. Key Lindbergh for many years wrote to legislators promoting Solar and Renewable Energy and many others.

    These Pioneers helped put Wind, Solar And Renewable Energy in the Spotlight for all the World to see. One of The Greatest Scientists ever Albert Einstein Stared it with a Dream that the day would come that all the World would use Solar Energy. His many years of work with the law of the “Photoelectric Effect”, and showing this to the World won him the Nobel Prize in Physics. For the “Photoelectric Effect”
    Free Energy From the SUN in the heavens above.
    We still do not teach this to our young.

    Very soon Hybrid Vehicles and (EV’s) Electric Vehicles will out number the ones that need oil and gas to go. With the ability to recharge them at home and work from the sun.

    Tesla Motors with its new Model S electric sedan, will be one of many the World will see soon. Honda, Nissan, Audi,VW, BMW and Volvo are just some of the Car Companies putting into production Electric Vehicles a EV, and many more are and many are building Electric / Hybrid Vehicles. The DeLorean Motor Company will be putting into production by 2013 a DMC-EV Electric DeLorean, that will have a body and power plant that will last you a life time. Just think you can recharge them at home and work free from the sun Solar Energy.

    Now to own a car that will never rust way and runs on the power from the sun that’s the one for me. Very soon most all on earth will be able to get energy by recharging from the sun and wind.

    Cities that want to be Clean clean-cities.org many of them are putting in recharging stations in their heart of their downtown of their city all over the Planet Earth. Many Thanks mostly to Scientist Bill Young and his team at FSEC for their many years of work at this..

    GOD Bless you Takashi Ohira and your team for the good work you are doing.
